Radial, also called lateral, vibration is the most commonly measured type of vibration in machinery. It involves the lateral, oscillatory movement of machine components in planes perpendicular to the long axis of the machine in a combination of rigid body and bending motion. Measurement and control of radial vibration is important because of the potential for unwanted rotor to stator contact during machine operation and because the cyclic bending stresses associated with vibration can lead to fatigue failure of machine components. While we cannot measure radial vibration in all places in a machine, it can be relatively easily measured with currently available transducers.
